Supervisory performances of PMSM using model reference adaptive control

Reference frame, disturbances are also considers in the process of integrations due to practical reasons, in the project a model reference adaptive control has been proposed to remove the disturbances in estimating the stator flux and to enhance the accuracy of the rotor angle estimation. Model reference adaptive control is a self-tuner, and in the project SVPWM has been used instead of using integrations for finding the rotor angle. By using SVPWM error can be reduced. The performance of the proposed sensor less method has been mainly assessed through simulation The rotor angle can be estimated from the stator flux in permanent magnet synchronous motor (PMSM). Although integrations are essential to estimate the stator flux from the voltages and currents in the stationary at low speed operations, senseless drive of PMSM is regarded as being extremely difficult without the signal injection. NOTE: Hear rotor angle estimation is done by MRAS (model reference adaptive control).
